Abstract
Adsorption of sulfonic acid doped poly(vinyl chloride) (PVC-SO3H) and poly(vinyl chloride) (PVC) on barium ferrite particles is described. T he maximum surface adsorption of PVC-SO3H on barium ferrite was twice that of PVC. Surface chemical interaction between the sulfonic acid gr oups and barium ferrite surfaces was examined by adsorption of toluene -4-sulfonic acid. Sulfonic acid groups were found to adsorb selectivel y on both Ba-OH and Fe-OH sites by an acid-base interaction. Increasin g the hydroxyl content on the barium ferrite surface creates increased dispersion stability in the presence of sulfonic acid doped PVC.
